Studies on effect of carbon based nanomaterial, novel plant growth promoting agents on growth of jasmine (Jasminum sambac Ait.)

Multi-carbon nanotubes (MWCNTs) having the average particle size of 71.81 nm with different concentration MWCNTs (3 and 7 g/L) graphene oxide a diameter 65.99 concentrations (20 40 mg/L), hydrogen rich water (500 ppb 1000 ppb) three sodium hydrosulfide (0.5 mg, 5 50 mg) as foliar spry along absolute control (Deionized water) were used spray at 15 days interval during 60 growth period in jasmine (Jasminum sambac). This study provided some insights into use carbon based Nano-materials. The multi-walled 3 g/L treated plants had maximum plant height (57.91 cm), internodal length (4.94 number leaves (170.55), spread E-W (46.01 N-S (55.69 Whereas, 20 mg/L showed promotional effect on attributes.
